This report presents the results of systematic reviews of effectiveness, applicability, other positive and negative effects, economic evaluations, and barriers to use of selected population-based interventions intended to prevent or control dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries. The related systematic reviews are linked by a common conceptual approach. These reviews form the basis of recommendations by the Task Force on Community Preventive Services (the Task Force) about the use of these selected interventions. The Task Force recommendations are presented in this supplement.

This review of U.S. dental schools' clinical curricula suggests that the basic structure of clinical education has not changed significantly in the past 60 years, although important developments include the introduction of competency-based education and community-based clinical education. Most dental schools still have a two-year preclinical curriculum and a two-year clinical curriculum, and most schools still operate a large clinical facility where students receive the bulk of their clinical education and assessment for graduation. In those clinics, dental students are the main providers of patient treatment, with faculty serving in supervisory roles. In addition, a major portion of the entire dental curriculum continues to be dedicated to student education on the restoration of a single tooth or replacement of teeth. This article was written as part of the project "Advancing Dental Education in the 21 Century."

One hundred twenty-four children identified as needing care in two elementary schools by a routine department of public health screening were randomly assigned to either a standard treatment group (notification to parents by a form letter) or an experimental group that added personal contact to the standard treatment. Overall, 53 percent of the subjects in the experimental condition who needed treatment at the initial screening had received this treatment at follow-up, while only 12 per cent of the subjects in the control group had received needed treatment.

The Task Force on Community Preventive Services is developing a Guide to Community Preventive Services (the Guide). Based on available evidence the Guide will summarize the effectiveness and cost-effectiveness of population-based interventions for prevention and control, and provide recommendations for people who plan, fund, and implement population-based services and policies. On behalf of the Department of Health and Human Services, the Centers for Disease Control and Prevention is coordinating support to the Task Force from governmental agencies, voluntary and professional groups, managed care organizations, and academia to develop and implement the Guide. Publication is targeted for the year 2000. Individual components will be published when completed.
